SetCPU works across the board as far as ROM's and OverClocking goes, it is definitely a keeper (plus the Dev deserves the few bucks), might I also suggest Root Explorer, also a few dollars, but it is the End All of file managment/explorer apps and will save you a lot of time and headaches in the future

BTW. Be sure to tell SetCPU to Auto detect your CPU when you try other Kernels. That way your sure you're getting the most out of it. PLUS I would set the batt temp profile to about 48 deg c. to clock it down. I didn't do this and had a temp problem and was in a constant re-boot. The only way I fixed it was by blowing air on the batt until I could program SetCPU to under clock the phone and then re-boot.
